Going to try and redeem myself now after my very confusing posts of last night. Ross has just explained that refractometer readings don't have the 10 in front - no wonder browndog was confused. Ross also answered my tannin questions - cheers mate! Will answer these and other questions below.
The Process
This was actually a very easy way to brew and would also be a very relaxing way if done at a reasonable hour and without interruption. (Please excuse pic quality).
Step 1 - Set Up Equipment. (5mins)
Step 2 - Fill Kettle with 33 Litres of Water and Apply Full Heat.
Step 3 - Raise Temperature to 72 Degrees for Mash In. (40 Mins)
Step 4 - Pour 6KG Grain Into Kettle. Stir and Check Strike Temperature Equals 66.
Will comment on Ross's Schwartzbier recipe and grains later. Agitated grain and stabilised temp at 66 within a few minutes.
Step 5 - Mash (90 Mins)
Maintained the temp with two applications of heat during the following hour and a half utilising these times to stir the mash as well.
Step 6 - Raise Mash Temperature to 80 Degrees (20 Mins)
This step may be 5 minutes or so faster when I do it again. I was worried about the grain at the base of the kettle getting too hot but apparently I was worrying about nothing. Last night though, I just hiked the bag up which was a bit of a job requiring teeth etc. Finally got it raised.
Step 7 - Remove Mash Bag
This step was also a little difficult. Holding 12 kgs up at an awkward angle is a pain but with a little thought, this problem could be fixed. I ended up dumping the whole bag into a
second vessel. In other words I broke the rules. I let bag self drain for about 15 minutes and then gave it a quick squeeze. From this I gained another 1.5 lts.
Step 8 - Bring to Boil (20 Mins?)
Was interrupted again at this stage which lead to the major error of using the incorrect hops. Wort actually tastes very good so fingers crossed.
All other steps are as normal so will not write them here. One final picture though of the trub left after syphoning from the kettle into the fermenter.
Efficiency - Excellent Results.
Lou and James: No extra grain was used and a 90 minute sparge was fine. Extra mash time gained nothing. Ended up with 23 litres with an Original Gravity of 1065 which is 9 points higher than Ross's Recipe predicts. It is also far higher than I have acheived previously brewing this recipe. Prior figures were 1054, 1050 and 1052. Using
this method raised efficiency from my usual 68% to 81%.
Recipe - Ross's Schwartzbier
3.37kg (56%) Munich Malt (9.0SRM)
1.93kg (32%) Pilsner Malt Craft Export (Joe White) (1.6SRM)
0.24kg (4%) Chocolate Malt (Joe White) (381SRM)
0.24kg (4%) Dark Crystal (Joe White) (110SRM)
0.12kg (2%) Carafa (337 SRM)
0.12kg (2%) Roasted Barley (Joe White) (710SRM)
38g Hallertau (5.3%) (80 minutes) 23.2 IBU
20g Hallertau (5.3%) (20 minutes) 7.0 IBU
20g Hallertau (5.3%) (2 minutes) 1.0 IBU
1 tsp Yeast Nutrient (10 minutes)
1 tsp table salt (90 minutes)
1 pkt Czech Pilsner Lager (Wyeast Labs #2278
I chose this beer as I have brewed it very successfully before (probably because Ross helped) actually using US-56 instead of a lager yeast. I thought that this is quite an easy brew for beginners as it allows those who can't maintain lager fermentation temps to still brew a beautiful lager. It is also a very forgiving brew. Last night involved extremely poor brewing practices by me but I'm still confident that this beer will be good.
Hope this post makes up for my poor posts of last night. Why I even posted last night I'll never know.
By the way, thanks to Smashed Jaffa, Ross, James for the kind and toally undeserved comments. My spirits would have been even further reduced without your comments.
A Great Way to Brew - So Far
I think I'm going to really enjoy my second bash at this on Saturday. I'm extremely impressed with the results so far and will filter and keg this batch in 10 days to see how it goes.* Only good part of last night was my good-looking female neighbour (not the 76 year old) also dropped in for a few beers - yum! Going to lock my doors on Saturdaymorning though to keep these 2 out...
Cheers
Pat
*Have had some yeast troubles lately and so picked up another pack and pitched it as well. Another stuck ferment would not make me happy!
